Disclosed are a method and device for protecting a mesh network, and the method includes: upon detection of a failure on a protected span, an end node located downstream of a signal stream on the protected span transmits an Automatic Protection Switch (APS) request signalling along at least one protection path of the protected span according to configuration information of the end node; and upon reception of the APS request signalling, an end node located upstream of the signal stream on the protected span transmits an APS response signalling along a relevant protection path, and performs a relevant bridging/switching operation according to its configuration information; intermediate nodes receiving the APS response signalling performs a relevant straight-forward operation according to respective configuration information; and an end node receiving the APS response signalling and located downstream of the signal stream performs a relevant bridging/switching operation according to its configuration information. By means of the disclosure, it is possible to improve the protection switching performance of the mesh network and enhance its robustness to failures. |
